MSD distributor tuning

TT5.9mag said

With the sliver bushing you should have a 25 degree swing. So 15 initial plus 25 mechanical would be 40 all in. You might have a weight hung up. Or something is up with the timing light or balancer. Could be you are not revving it high enough to see all the mechanical come in.

So, I had both weights off when I changed the bushing and they move freely. I bought a new adjustable timing light for this to check against my old, non-adjustable one and both read the same. I revved the motor pretty high and would not go past 30* . The distributor is relatively new <5000 miles on it. I think it
Is the springs, but I do have a set of weights that I can swap if needed if changing to lighter springs do not help.
